Ridge Vent

Ridge vents come completely assembled for ease of installation. Ridge vents supplied by Metal Building Depot are of a low profile design to provide gravity type ventilation. Because gravity ridge vents are designed to allow free airflow, some penetration of water during blowing rains is to be expected. Standard available finishes for the ridge vents are polar white and galvalume. Other colors may be available at an additional cost. Nominal ridge vent length is 10'-0". Ridge vents are available with 9" and 12" throats. Bird screens are provided as a standard. The ridge vents can be ordered as continuous or single units. Exterior parts are 26 gage painted or galvalume. Interior parts are all made of G90 galvanized steel. The substructure consists of 10 gage saddle straps with interior baffles of 24 gage steel. Lifter arms and damper slides are made of 18 gage steel. Manual operation is through activation of a pull bar which is attached internally to bell cranked type lifter arms connected to the damper with Teflon coated pins through the damper slides. Dampers are spring loaded to remain in the open position until the pull bar is operated and locked in the closed position. Dampers operate in a vertical manner. Each vent is opened by a pull chain that extends approximately 12" below the roof unless noted otherwise on the order documents. Other opening mechanisms are available at an additional cost upon special request. Ridge vents should not be placed closer than 5’-0" to the endwall steel line to allow room to properly flash the building. For example, a 90’-0" long building with ridge vents required the entire length should have no more than (8) units. The ridge vents are available with the following accessories:

Metal Building Kit

Purchasing your new metal building kit. You should be cautious when buying a metal building kit. Not every manufacturer uses high quality materials or fabricates to the latest industry standards. You don't want to purchase a building from a manufacturer (or broker) whose building parts were produced in a factory without the benefit of a skilled eye to oversee the process.

A pre-engineered metal building should come with a complete and comprehensive set of blueprints. When a qualified steel building manufacturer puts its seal of approval on your building design you can rest assured of its structural integrity. You can expect detailed documentation about the building's fabrication and its specific code requirements as well.

Before you purchase a metal building kit you should attempt to create a basic plan for its end use and design. Working with a professional steel building company should ensure that all facets of your building are taken into consideration. They can explain the building options and codes in detail so you have the accurate building specifications.

General Guidelines

When you decide to buy a Building - Confirm the accuracy of your building codes. It is imperative that your building conforms to the state, local and federal design requirements.

The items described on your contract are what you are buying. Please be sure to carefully review all contract documents before you sign off. If a contract does not describe an item in specific terms, you should not expect the item to be the best product available. And just as important - is what a contract does not say. Specifically if your contract does not indicate that you are getting framed openings and garage doors - then you are NOT going to get framed openings and garage doors.

Do not sign a contract or agree to purchase a building before you have confirmed that your building will satisfy the requirements of your local building official and YOURSELF. Do not allow a salesman to pressure you into a "panic buy." A "panic buy" is when a customer is pressured into making a purchase to "lock-in" a "so-called" special price. Brokers are notorious for telling customers they could lose an opportunity to get the "deal of a lifetime" if they don't commit to the order right away. Beware of people who urge you to sign a contract before you have made your mind up on exactly what you want.

Understand that making changes after the sale will cost you money. Once the design is completed it will cost money to make changes. If an order is in fabrication - and requires modifications due to customer demands - the entire process has to be stopped, pulled off-line and inventoried. Once the inventory of completed items is confirmed, it's back to the drawing board. You will be responsible for extra time required to re-design the project and all other associated expenses.

Install your building components as specified by the drawings. Seldom do manufacturers use the same design practices and therefore your erection drawings and installation documents are the correct description of the building. Please read and follow the drawing descriptions carefully. An erection manual offers important general guidelines and the proper procedures for erecting a steel building safely. You, your erector and all jobsite crew need to understand and utilize OSHA and all other safety guidelines.

Perm Rating

The perm rating, or permeance, is a measure of the amount of water that passes through one square foot of material per hour. The lower the perm rating, the more effective the barrier. A facing material with a perm rating of 0.1 or less is considered excellent. Anything with a rating above 1.0 is not considered a vapor barrier.

Panel Profiles

Roof Panel Profiles - Our standard roof sheeting is the "PBR" panel, which is available in bare Galvalume Plus® as well as a variety of colors. Wall sheeting is available in "R" and "PBR" panel. Depending on the color and your geographic location - PBR panels may not be available for certain colors.

Liner Panels - For liner panels we offer a low-rib 29-gauge panel. Liner panels are an interior covering for the walls of a steel building. Like exterior walls, liner panel consists of 3-foot wide panels that are attached to the framing in the same manner as exterior sheeting. Full-height liners run from floor to roof. Partial-height liners typically attach to the girt at 7'4" and extend a few inches above it. Buildings with liner panels must have a base connection for the bottom of the panel (see base conditions).

Advantages - Liner Panels enhance appearance, providing a finished look for the interior. The biggest advantage is that liners protect the insulation and the outside walls. Because un-reinforced insulation facings tear easily, and even the best-reinforced materials can be damaged, liner panels are the intelligent solution to protect your investment. Although 26-gauge exterior walls can withstand a lot of punishment, a steel liner will protect your building's interior and performs at a lower cost than other wall coverings, which will require their own framing.
